Exact-Match 192 GB Server Kit

This 192 GB kit contains four 48 GB DDR5 RDIMMs rated at 6400 MHz PC5-51200 with CL52 latency and 1.1 V operation. The modules are 2Rx8 registered ECC memory built for Supermicro H13SRA-F and H13SRA-TF motherboards. They install as a matched set so the controller recognises the full capacity at rated speed.

Registered ECC Changes Daily Operation

Registered buffering offloads the memory controller, allowing all four slots to run fully populated at 192 GB without signal degradation. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads. The kit includes no heat spreader, relying on server chassis airflow for cooling.

Check Motherboard Population Rules First

Supermicro H13SRA-F and H13SRA-TF boards have specific DIMM population orders and maximum capacity limits per channel. Consult the motherboard manual for the approved slot sequence and any BIOS version requirements before installing. This kit is not compatible with UDIMM or SODIMM slots and requires a platform that supports DDR5 registered ECC RDIMMs.

Questions about this item

Will the 288-pin DDR5 RDIMM modules need any firmware updates or physical maintenance after installation?

No firmware updates are required; the registered ECC DDR5 modules are recognised at full 192 GB capacity on the supported Supermicro boards and have no moving parts or heat spreaders to service.

What limits sustained throughput when all four 48 GB sticks run at 6400 MHz CL52?

The memory controller on the H13SRA-F or H13SRA-TF motherboard is the first bottleneck; the kit already matches the board's maximum validated speed and rank configuration.

How much heat and power do the 1.1 V 2Rx8 modules generate during continuous all-day operation?

Each module operates at 1.1 V without a heat spreader, so thermal output stays low and the registered design keeps power draw predictable for server chassis airflow.
